will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to certain new and useful improvements inapparatus for manufacturing hollow glassware, of which the following isa description.

This invention has particular reference to that type of moldingapparatus in which a sectional mold is employed and into which isprojected a hollow core, the latter during its projection orlongitudinal movement having imparted thereto by suitable mechanism arotary motion. The mold is of the sectional type.

Reference will be had to the accompanying drawings, forming a part ofthis specification, and in which like numerals of reference indicatecorresponding parts throughout the several views, in which Figure 1 is aview in elevation of the mold, showing parts broken away and in section.Fig. 2 is a top plan view of the carriage for projecting and rotatingthe mold. Fig. 3 is an end elevation of Fig. 2; and Fig. 1 is afragmentar y view of the shaft, rotating gear therefor, and means forpreventing the gear from moving with the shaft except in a rotarydirection.

Reference-numeral 1 designates the lower section of the mold, and 1 theupper moldsection, the latter being capable of being swung upwardly bymeans of hinges 2, through all of which passes a pintle 3, provided withoperating-handle 4. The mold is formed of a plurality of sections andmay be of any desired length, according to the number of sectionsadopted. The sections of the mold are formed with peripheral tracks 5,whereby the mold is supported for partial ro tation upon rollers 6 onthe upper ends of standards 7 Through the open rear end of the mold isprojected the core 8, which is hollow, whereby compressed air may besupplied to the mold from pipe 9, suitably attached to the core. Theglass article, which is formed between the core and mold, is thoroughlycompressed by the compressed air which escapes from the core throughvalve-controlled port 10. This air pressing against the inner surface ofthe glass article insures a thorough contact throughout of the outersurface of the article and the inner surface of the mold. The flange 11.of the rear end of the mold guides the core during its entry.

The means for projecting the core consists of a carriage 12, suitablymounted on tracks and provided at its top with a longitudinal rack 13.At one side of the carriage are arranged standards 14, in the upper endsof which is journaled a shaft 15, provided with a gear 16, which is inmesh with and is operated by a gear 17 on a shaft which is operated by acrank 18, suitably operated.

For imparting a movement in a rotary direction to the coresimultaneously with its projection by the carriage a worm-collar 19 isprovided. This collar encircles the core and is provided with a keywhich operates in slot 20, formed in the core and longitudinallythereof. gear 21,meshing with asimilar gear 22, which is on. the upperend of a shaft provided at its lower end with a worm-gear 23, the latterbeing in mesh with worm gear or collar 19 to impart a rotary movement tothe core. This last-mentioned shaft is mounted in a bracket extension 24of one of the standards 1 1, and from this bracket project two fingers25, embracing both sides of the worm gear or collar 1 9 to prevent thelatter from moving in a longitudinal direction with the core as thelatter is projected. The rotary movability of the core and mold enableseither to be rotated separately or both together either in the same oropposite directions, thus greatly facilitating the operation, es eciallythe removal of the core and the artic e being molded.

On the shaft 15 is provided a bevel-j Having fully described theinvention, what is claimedas new and useful, and desired to be securedby Letters Patent, is

1. A molding apparatus comprising a mold, a core, and a carriagesupporting said core and for projecting the core into the mold, andmeans for rotating the core during its projection.

2. A molding apparatus for hollow ware, comprising a mold rotatablysupported, a core, a carriage supporting the core, means for moving thecarriage longitudinally to project the core into the mold, means forrotating the core during its entry into the mold, and means forsupplying compressed air through the core to the mold.

3. A molding apparatus for hollow glass- Ware, comprising a mold formedof a plurality of sections each made up of half-sections, means forseparating the halfsections, means for permitting rotation of the mold,a core, flexible means for supplying compressed air to the core,valve-controlled means for allowing the air to escape from the core intothe mold, means for moving the core longitudinally into and out of themold, and means for rotating the core during such movement.
